Komy Cree LED Lighting on Bicycles?

Komyís lights have been used by many Motorcycle enthusiasts with Great results! I plan on using his High Lumen Lights on my Triumph Tiger. I got to thinking why not on the Bicycle? So I thought I would ask!

Anyone here use these lights? Komy has a New Single Cree 900 Lumen 12 watt light that he says bicyclist seem to like. I also like his 3 Cree LED 780 Lumen He does not provide battery packs so thatís something we would have to work out ourselves. These kits are for pairs but if you email him he will quote prices for single light kits.

I have a few different Light Packs all 8.4Volt running 2600mah 2-18650, 6400mah 4-18650 & 12,800mah 8-18650. So I have options for length of running time or how many lights I want to run.

Iím not advanced enough to build my own LED Light Sets so purchasing what is out there is best suited for me.

Komyís light kits come with all you need to wire em up to a battery source with switches, fuses and even dimmers. Itís not a plug & play like most of the bicycle lights Iíve seen but with the savings that are had doing it this way, youíll have the funds for any custom wiring you may want to do! He has a new Hard Wired Dimmer Switch that should be available soon that gives you many options for percentage of power and flashing and is very much smaller then his remote dimmer!

Anyway, Iím weighing the advantages and disadvantages trying to figure out which way to go!??

Don't know. I have no hands-on experience with that brand and just looking at the specs - the wattage just doesn't make sense. No 12V LED that I'm familiar with draws anything near 12W. Mine draw 0.75W each.

The idea works OK and I'm running an automotive system myself because its more robust than bicycle lighting systems and still so light the additional few grams is irrelevant - and the additional durability pays off. But you'll have to watch your batteries. Without a BMS you can accidentally run individual lithium batteries down below 2.6V which pretty much trashes them.

There are similar LED lights on the market already set up for off-road motorcycle use that have built-in voltage regulators and 5.6Ah battery packs that'll run them for 9 hours if disconnected from an automotive electrical system. PM me and I'll point you to a few places.

Yeah zacster they are similar to what I have been seeing out there except he builds these mainly for Motorcycle & Automotive Applications. The quality is Very High and heís a stickler for Customer Service! He goes out of his way to make things right when there is a problem and we all know when it comes to electronics there can be problems! He admits heís really not up on the Bicycle side of things but he has had Motorcycle & Car purchasers of his lights inquire about use for Bicycles.

Yep, the whole wiring thing is something that needs more thinking out as they are Not Plug & Play like the Bicycle Specific Lights. They are heavy on battery drain so Packs would need to be substantial for long runs but it can be done! Switches, Dimmers and making the Wiring look nice on the Bike are all added dimensions!

The Pricing is Great for the Quality! Better Pricing then all those Name Brand Lights posted through out these forums with Quality as good or better! Like I said they are going on My Triumph Tiger! But when you can get an 1800 Lumen Bike Light with Battery Pack for $25 Bucks you have to question? Plus the $25 Lights are Plug & Play!

Hey Burton: I'm not electronic savvy but from what I understand it's the Drivers he uses to Maintain the High Consistent Lumen Output! His lights do pass what ever tests that have been done on actual Lumens they do draw right on the Watts he states as has been tested by many Tiger owners with there voltage/wattage meters on their Bikes! These Lights are Ridiculously Bright! Will Burn Your Retinas! One reason why he offers the Dimmers with his kits! Komyís 30 watt set up with Dimmer plus 9 watt for Running Lights are going on My Tiger mounted on a SW Motech Bar under the Nose!

Batteries have been the main discussion here with the Bicycle Guys around me. We have been trying to figure out what we would actually need to Run these Lights or would we be better off just getting the Bike Specific lights with their matched battery Packs? Again none of us are electronic savvy so all the questions!

You mention the BMS? Not sure what that is but I know that some of these Battery packs have built in electronics to keep them from being over charged or over run! Is that not enough? And what would this BMS afford us?

PS: Hey Burton; Can't PM you to much of a Newb not enough posts! Can you PM me with the info? Or post here? Thanks

OK - my bad anyway. It was too early in the morning and was thinking amperage instead of wattage. So the wattage numbers are still higher than what I'm expecting but could be a result of overdriving them. Will PM you.

So If I understand the math, these lights will pull about 2 amps, per hour?

I am research lights for an e-bike build, so am thinking about these for that project.

I like the size, and the results I have seen with images and video on google.
Just not real sure how the electric will work.

I will be using a 48v 15ah LiPo battery for the bike, with a 1000w motor, and will put a 48v to 12 v regulator in there. The bms is included with the e-bike kit.
Thanks for any opions on this set up, for the lights.

There are already 10W lights on the market that use a light engine that will accept a direct input of anything from 9VDC to 48VDC and draw about 0.75A each. Should be a no-brainer.

Yes, you divide the amp-hours of a battery by the amp draw of the device to get the time expected from the battery before it dies. And don't expect the battery to really last that long because the battery ratings aren't that reliable.
